Description:

Privacy and light protection for windows or room dividers, whose segments can be adjusted around two axes at the same time and can be pulled up.

The privacy and light protection combines the possibilities of blinds and slatted curtains. The view or the incidence of light can be interrupted horizontally and vertically or as a mixed form. The view or incidence of light can be interrupted completely, partially or not at all, depending on the setting.

The invention is based on the problem of developing a visual and light protection made of movably connected segments, which are to be suspended in such a way that all positions between full dimming and the lowest vertical or horizontal dimming can be continuously adjusted.

This problem is solved with the features described in the protection claim.

The invention offers several advantages. The segments can be aligned perpendicular to the incident light at any position of the sun, thus providing optimal shading while simultaneously providing the greatest possible visibility. The advantage over blinds or slats is particularly evident when the sunlight falls at an angle. Targeted privacy protection is also possible in the same way. The fact that the individual rows of segments can be raised independently of one another opens up further possibilities for shading rooms individually. Last but not least, segments of a wide variety of shapes can be processed.

An embodiment is explained using Figures 1-6. They show:

The privacy and light protection consists of several segments that are hung next to and below each other, as shown in Figure 1. The square shape, as shown in Figures 1 and 2, is a design but not absolutely necessary, other variants are shown as examples in Figure 6. Likewise, the

Size can be adjusted to the desired optical effect. The segments are always connected to the segments above them by cords 11 at exactly the same distances. A connection to the segments hanging next to them is possible but not absolutely necessary.

Figure 3 shows two possible designs for attaching the cords to the segment corners. Both allow for subsequent adjustment of the cords. In the first variant, the cord 11 is guided through a metal ring that is glued into the segment corner and fixed with a grub screw 14. In the second variant, a hole 12 is drilled in the segment corner, the cord is passed through with a half hit and clamped with a suitable screw with nut 13. In order to allow the cord to run exactly over the corner, the corner is milled out semi-circularly.

The uppermost segments can be rotated about axes 1 and 2 (see axis diagram in Figure 1). This adjustment is passed on to the lower segments by the suspension. Transferring the rotation to segments hanging at the side is possible depending on the design, but not shown here. The segments can be pulled up like blinds using a centrally running cord 16 (the cord can be seen in Figure 1, a simple type of eyelet design 10 in Figure 4). The segments hanging one below the other can overlap one another if the bracket 3 is swiveled into a vertical position and the length of the cord sections 21 is less than the height of the geometric figure on which the segments are based. If the segments are to hang butt-jointly, the height must correspond to the cord sections. Overlapping segments hanging next to one another is not advisable.

The adjustment around the transverse axis 2:

The privacy screen segments are suspended from a pivoting bracket (see Figures 1 and 4). The rotation axis 9 of the bracket runs horizontally through the center of the longitudinal and transverse axes of the top light and privacy screen segments. These are attached to the bracket via an axis 4 so that they follow the pivoting movement. The movement of the bracket is thus transferred from the upper segments to those hanging below via the suspension or cords. The segments are positioned horizontally like a blind.

The adjustment around the longitudinal axis 1:

Figure 2 shows the connection of the uppermost segments to the bracket. The axle 4 is firmly screwed to the segments in the direction of the longitudinal axis and is mounted so that it can rotate in the bracket. A gear 18 on the axle transmits the movement of a chain running in the bracket to the segments. The chain in turn is operated by a crank 19 guided laterally in the bracket (Figure 4). Regardless of the position of the bracket, the segments can be moved around the longitudinal axis by turning the crank.

The winding

The lower segments can be pulled up to the topmost ones using a simple pulling mechanism. A cord runs freely through the holes 20 in the middle of all the segments in a row, as shown in Figure 1. At the end of the cord there is a resistance which, when pulled up, raises the lowest segment and, in turn, the segments above it. The cords in each row are diverted via eyelets or rollers on the frame and are to be attached to a clamp (not shown). Any step between fully lowered and fully raised is conceivable and independent of the setting. Likewise, partially raised rows of segments can still be adjusted as desired. Once all the segments in a row have been fully raised, the bracket can be pulled further towards the frame when adjusted horizontally (Figure 1). The bracket runs a little way up on slides 6 in the lateral guide rails of the frame. Slides 6 and guide are shown in Figure 5. Figure 4 shows a representation of the frame, slide and bracket. The option of tightening the bracket is interesting for installations in window cutouts where the windows are to be able to be opened completely.

Claims (6)

1. Privacy and light protection for windows or room dividers, which consists of several segments and a device for hanging and adjusting them. Characterized in that in at least two rows at least two segments are suspended one below the other and can be rotated about two axes ( 1 and 2 ) which run in the plane of the segments through the center of the same and are perpendicular to each other. 2. Visual and light protection according to protection claim 1, characterized in that the rows of segments can be pulled up individually and completely and that the adjustability is independent of the pulling up. 3. Visual and light protection according to protection claim 1, characterized in that the adjustment about the transverse axis ( 2 ) is carried out by a bracket ( 3 ) to which the uppermost segments ( 8 ) of each row are attached and which can be pivoted about an imaginary axis ( 9 ) running horizontally through the centers of the segments. 4. Visual and light protection according to protection claim 1, characterized in that the adjustment about the longitudinal axis ( 1 ) is carried out by rotating the axes ( 4 ) mounted in the bracket ( 3 ) for suspending the uppermost segments. 5. Visual and light protection according to protection claim 1, characterized in that the lower segments of a row simultaneously follow the adjustment of the uppermost segment due to their parallel suspension ( 5 ). 8. Visibility and light protection according to protection claim 1, characterized in that the bracket ( 3 ) can be pulled upwards on slides ( 6 ) on both sides in a frame ( 7 ).
